Answer:
P(heads appears on only the last toss) = 
Step-by-step explanation:
A fair coin is tossed 3 times in a row.
When a coin is tossed we get a tail or head T or H
The possible outcomes of 3 coins are
T T T , H H H , T H H, H T H, H H T, H T T , T H T, T T H
So total of 8 possible outcomes
heads appears on only the last toss , first and second toss should be tail
So its T T H. Only one possibility
Probability(any event) = number of outcomes / total outcomes
P(heads appears on only the last toss) =
Answer:
<em>The shop made a profit about $40.</em>
<em>Step-by-step explanation:</em>
<em>Now, According to the question We know that :</em>
<em>The shop marked the $200 price up by 60%.</em>
<em>60% of $200 is = $120. </em>
<em>Now, the price is = $320 because, 200 + 120 = 320. </em>
<em />
<em>Joseph bought the tennis racket at 25% off.</em>
<em>25% of $320 is = $80.</em>
<em>Now, the discount price is = $240 Because, 320 - 80 = 240.</em>
<em />
<em>So, Joseph bought the racket for = $240.</em>
<em />
<em>Now we know that the original price from the factory was $200.</em>
<em>Joseph bought it for $240.</em>
<em>So, the shop made a profit of $40.</em>

The number of students in 5th grade is 60, since 24% of 250 is 60.
Since 90 is 38% if 250, 38 is going to be the percent of all students in sixth grade.
20% of 250 is 50, so the percent of all students in seventh grade is 50.
Finally, 45 is 18% of 250, so 18 percent of all students are in eight grade.
Hope this helped :)
